The paper is devoted to a linear crack located between two dissimilar
elastic half-spaces under normally incident harmonic tension-compression loading.
The system of boundary integral equations for displacements and tractions is derived from the dynamic Somigliana identity. The dynamic stress intensity factors (the opening and the transverse shear modes) are computed as functions of the loading frequency taking the contact interaction of the opposite crack faces into account. Theresults are compared with those obtained neglecting the crack closure.
